I have one farm that is running 2003 MFXPa FR3, when an admin logs into the desktop we are getting queued errors popping up, usually Explorer.exe faulting module ntdll.dll but I have also seen quicktime, IE, Outlook. Any idea what could be causing these errors? I am not getting complaints from my users but that doesn't mean they aren't getting program errors and not telling me.
